SUPPOR'I.` FOR MOLDBOARDS.

Specification of Letters Patent.

Patented Aug. 10, 1915.

Application filed January 26, 1914. Serial No. 814,377.

T0 all whom it may concerny Be it known that I, DENIS WILLIAM DALEY, av citizen of the United States, residing at Parkersburg, in the county of Wood and State of lVest Virginia, have invented new and useful Supports for Moldboards, of which the/following is a specilication.

My invention generically appertains to mold forms for the construction of concrete walls and the like, but more essentially to that class of form adapted to be constructed in courses.

One obj ect of my invention resides in providing a mold form for concrete walls and the like, wherein the mold boards comprising the form are constructed in courses, one above the other, and may be removed from the set or hardened portion of the concrete wall and disposed upon the uppermost courses of boards so as to form a continuatlon of the mold form as the construction of the wall progresses upwardly.

A further object of this invention resides in providing a series of supports having means connected thereto and projecting laterally therefrom for coperation with cer tain other means secured -to mold boards whereby the latter may be properly supported in vertical position.

Another objectof my invention lies in providing a novel means for bracing the mold board against the lateral thrust of the end construction.

Another and still further object of this invention resides in so constructing the mold form that the lowermost course of mold boards forming the latter, may be readily removed without disturbing the course of mold boards disposed above it.

With these and other' objects in View, my invention consists of certain novel details of construction, arrangement, and combina* tion of parts to be more particularly set forth and claimed.

In the accompanying drawings in which corresponding parts are indicated by similar reference numerals, Figure 1 is a fragmentary perspective view, partly in section, illustrating a partially constructed wall having my improved mold boards removed and disposed upon the uppermost course thereof; Fig. 2 is a horizontal lsection taken on the line 2-2 of Fig. 1; Fig. 3 is a fragmentary perspective view of one of the mold boards illustrating the latter in connection with my improved bracket for supporting the same; Fig. 4 is a fragmentary perspective view of a modified form of my improved mold illustrating the latter in connection with the partially constructed wall; Fig. '5 is a transverse vertical section of the form shown in Fig. 4; Fig. 6 is a perspective view of a modified form of lmold bracket; Fig. 7 is a transverse vertical section taken on the line 7-7 of Fig. 5; Fig. 8 is a horizontal section taken on the line 8-8 of Fig. 7; Fig. 9 is a side elevation partially in section illustrating a modified form of the means for preventing lateral movement of the mold board; Fig. l() is a horizontal section taken on the line 10-10 of Fig. 9; Fig. 11 is a transverse vertical section illustrating a modified form of supporting bracket for the mold board, and Fig. 12 is a horizontal section takeny on the line 12-12 of Fig. 11. y

Heretofore in the construction of concrete walls it has been customary to either build the form to thelproposed height of the desired wall, or else construct the forming vcourses as the wall progresses upwardly, in

the latter case, however, the boards used in constructing-the lower portion of the wall are left in place and new boards added to those to increase the height of the form. Thisghas been found disadvantageous, however, because, in the first place, it required quite an outlay of lumber in order to provide the necessary mold board, and secondly, that after the wall had been constructed, the boarding used was what might be termed as dead lumber, and had to be sold at a loss to the party constructing the l wall. To this end I propose to provide a form which reduces the number of parts required to produce a wall of a given height, inasmuch as it enables the lower mold boards to be removed after the concrete has set or hardened, and used in forming the upper portion of the Wall, furthermore, the entire form may be continually reused for other construction work, as will be readily understood without further description.

In view of the foregoing, I propose to provide a plurality of angular standards 1 which are arranged in pairs, the members of each pair being oppositely disposed and situated in spaced relationship, as clearly shown in Fig. 1. Mounted upon each of the standards 1 are aseries of brackets 2 which are formed in two sections -3 and 4 respecangles to that of the former. Section 4 of the brackets 2 has its outerend extended laterally as at 5, and provided with a centrally arranged aperture 5 for a purpose hereinafter to be set forth. Also projecting laterally from the section 4 contiguous to the extremity 5 thereof, is a tongue 6 which cooperates with said extremity 5 to form a seat adapted to engage with each of said standards. In order that the brackets may be permanently maintained in their adjusted positions, I provide a set screw 7 which passesy through the openings 5 and engages the outer surfaces of the standards to secure said brackets in their proper position and relation. The outer extremity of section 3 of the brackets 2 is provided with the oppositely projecting flanges 8 which, when the mold boards 9 are arranged edgewise one above the other, project in the channel 10 formed in the channel irons 11 which are disposed upon the longitudinal edges of said mold boards 9 and securely support the latter in proper position to form a unitary construction, as will be readily understood without further description. I have found in actual practice, however, that it may sometimes be desirable. to replace the angular standards 1 with the annular posts 12 which latter are provided at predetermined points thereon with the cross shaped openings 13 which receive the reduced extremity 14 having the enlarged head 15 of the mold board support bracket 16. From this construction it will be seen that when the enlarged head 15 of bracket 16 is passed through the enlarged portion of opening 13 and projected downwardly into the reduced portion thereof, said head will be locked in position and consequently the bracket 16 cannot become disengaged. Furthermore, to increase the stability of-bracket 16, I provide the inner surface of post 12 on opposite sides of the reduced portion of the cross shaped openings 13 therein with studs 15 which it will be seen frictionallyengage the inner edge of the enlarged portion 15 of the bracket and assist in maintaining the latter in proper rightangular relation to the post12.

The outer extremities of brackets 16 are provided with oppositely projecting flanges 18 which enter the channels 10 of the mold boards and support the same in position, as described in connection with the first mentioned brackets. Owing to the severe lateral thrust placed upon the mold boards 9, I propose to strengthen the same by placing a series of blocks 19 at predetermined points on the outer surfaces of each of said boards, which blocks'engage the arcuate extremities of the bracing rods 20, said rods having reduced ends 21 which project within suitable openings 22 formed in post 12, which cona struction provides an absolute preventive against all lateral movement on the part of said moldboards 9.

In lieu of the bracket 16 and means for bracingv the same as j ust described, I may substitute the brackets 28 which latter are hingedly connected as at 29 intermediate their ends, the hinged connection being so arranged that each pair will open oppositely. By hingedly connecting the brackets in this manner, the same are formed in two sections 28 and 28, the latter has its outer extremity threaded as at 30, and passed through the registered openings 31 so as to. project `from the opposite side of the post 12 and to bracing rods 25 which latter have an eccentrically mounted wheel 24 at one end there* of to coperate with the wedge-shaped blocks 23; the other extremity of said brac* ing arms 25 being reduced as at 26 to project within suitable openings 27 formed in post 12. Thus it will be seen that I have provided a mold form which may be readily transferred from place to place and reused when necessary, as well as one so constructed that the mold boards constituting the form may be removed during the construction of the' wall or the like, and reused in the ,furtherv construction thereof, which consequently greatly reduces the cost in erecting concrete structures, and is in every way far superior to the molds now in use.
